Comet Tempel 1’s nucleus appears as the red blotch at the center of these false-color views based on Deep Impact observations from May 30, 2005. The actual image is on the upper left with a mathematical model Tempel 1’s atmosphere to right. The lower left image shows the difference between the two upper views, yielding Tempel 1’w nucleus. At bottom right, a trace through the center of the comet shows the brightness of the nucleus. Credit: University of Maryland/NASA/Ball Aerospace. Click to enlarge.
